Hmm its a little different format than mine prolly because your using pro.Do you know if those responses match the 16bit address of your remote xbee? You can check if you read the remotes modem parameters. it should be under Addressing (SH Serial High, and SL serial Low)

If those numbers match then its not making sense why it isn't printing anything out. It seems to be communicating correctly.

There might be a quirk with the modules that your using that are different than the ones im using. If I think of anything Ill let you know. Its probably going to be something simple we are both missing.

Yeah I checked the 16bit addresses and they did match for both of the modules, yeah please let me know if you think of anything else...Thanks again for all the help, I'm doing this for a school project and have been stuck for a good couple of weeks.

Its wierd that you are recieving 00 hex in X-ctu. That is NULL. Im still going back to hooking the Dout pin to an arduino's RX pin and trying to view the incoming data that way. I think it should work because a logic level high I think is 3V. Just don't hook it up with the TX going directly to the Xbee. Im not sure however if you will need to take the Atmega chip out or not. Try just plugging the arduino board in and starting the Arduino software then going to the serial port. Make sure the arduino IDE is set to 9600 baud. Then plug the DOUT into the RX.

I tested the code you were using last night and it came accross fine on my computer. I havn't tested it with the setup described above however, and I won't be home to test it for about 9 hours.

Let me know if your going to try this. You might just get a bunch of random crap if the voltage out of the xbee isn't high enough. Im learning as we go as well.

I've tried your idea with connecting the DOUT pin to the arduino and it did not print anything. Someone suggested trying to use hyperterm instead of XCTU so I am going try that tonight and see if I can get anywhere with that.

now I wonder what i can do to circumvent this in my setup :-/the reason (probably?) it works one way in my system is, that for the pc-connected xbee i use the LilyPad Xbee board, and on the other (not working) side it's the explorer board

I have the lilypad on the computer via an fdti-usb connector and it works as intended.

however, the explorer on an arduino does not workI saw you posted on the sparkfun comments and assume you have the same issue using an xbee 900.

one solution would be to buy the pallax or adafruit module but I would prefer to keep the money to myself oooh... well too simple: I could switch the lilypad and explorer so the lilypad is the sender, because I'll use it as one way connection anyway

My problem was the xbee explored connected to the arduino did not work for some reason, it only sen out null data. I instead got an xbee breakout boardroom connect the xbee to the arduinohttp://www.sparkfun.com/commerce/product_info.php?products_id=8276. Try this, it is a cheap solution that worked for me, i don't know why the xbee explored did not work.

just tested it by switching the lilypad and the explorer: it works.I assume it's what the people tell in the sparkfun forum: the explorer is too weak for pro or 900 xbee modules to let it send - receiving still works because it does not draw so much current
